(…and don’t forget Schizotypy!)

There are many disorders within the mental health field that begin with the prefix “schizo-¹” which means “split” or “schism” (This is different from the splitting that occurs in borderline personality disorder² ³🤯). Other than the actual name of these disorders, why is it so confusing to understand the differences among them?! In order to answer this question, we need to dive into the similarities and differences of schizoid, schizotypal, and schizophrenia! …and then another construct called schizotypy…because we had to make it even more complex🤦.

Definitions¹

Schizoid personality disorder is a pattern of social detachment and restricted emotional expression…plus 4 or more criteria involving:

Not wanting, enjoying, and/or lacking close relationships
Lack of interest in sexual experiences
Choosing solitary activities
Not taking pleasure in things
Appearing indifferent to praise/criticism
Showing emotional coldness, detachment, or flattened affectivity.
And remember: there’s no psychosis or autism.

Schizotypal personality disorder is a pattern of social/interpersonal deficits, including extreme discomfort with, and decreased capacity for, close relationships AND cognitive/perceptual distortions and behavioral oddness…plus 5 or more criteria involving:

Ideas of reference
Odd beliefs/magical thinking, thinking/speech, and/or appearance/behavior
Unusual perceptual experiences
Suspiciousness/paranoid ideation
Inappropriate/constricted affect
Lack of close relationships
Excessive social anxiety related to paranoid fears
Also, just like schizoid personality disorder, there’s no psychosis or autism.

Schizophrenia is a psychotic disorder characterized by 2 or more symptoms of delusions, hallucinations, disorganized speech, disorganized/catatonic behavior, and negative symptoms, but one of the symptoms must be a positive symptom (delusions, hallucinations, disorganized speech). The symptoms have to occur often during a period of 1 month with continuous signs for at least 6 months.

Here, you can find the exact DSM-5-TR criteria for schizoid personality disorder, schizotypal personality disorder, and schizophrenia.

Schizophrenia vs Schizoid vs Schizotypal Venn Diagram

How do they overlap?

Schizoid and Schizotypal are both “Cluster A” personality disorders involving social isolation, interpersonal issues, and restricted affectivity¹. Also, we have a lot of research about the “schizoid-schizotypal” continuum. Schizotypal and Schizophrenia are both part of the “Schizophrenia Spectrum and Other Psychotic Disorders” in the DSM-5-TR1 and ICD-11. Schizoid and Schizophrenia both can have negative symptoms¹, and some consider schizoid to be a “subsyndromal schizophrenia spectrum disorder².” The view that schizoid personality disorder is on the schizophrenic spectrum is highly debated. Additionally, some believe schizoid, schizotypal, and schizophrenia are all on the same personality line,⁴ ² ³ but again, this is highly debated.

How do they differ?

	Schizoid	Schizotypal	Schizophrenia
Categorization	Personality Disorder¹ schizophrenia spectrum?⁴ ² ³	Personality Disorder¹ Schizophrenia Spectrum¹	Schizophrenia Spectrum¹
Reality Testing	Intact (no psychosis)¹	Borderline (no psychosis; blurs the line of reality)¹	Not intact (psychosis)¹
Emotions	Detached/lacking¹ Low neuroticism⁴	Inappropriate/restricted¹ High neuroticism⁴	Increased suicide risk¹ High neuroticism⁴
Self	Low self-consciousness¹ ⁵	High self-consciousness¹ ⁴	Variable self-consciousness¹ ⁴
Interpersonal	Disinterested/detached¹	Anxious/uncomfortable¹	Proprioceptive oddities⁴ (no social-related criteria)
Impairment	Potentially less than⁴ →	Medium⁴	Potentially high⁴

But wait! There’s more…

What is Schizotypy?

In the research about schizophrenia particularly, there’s been exploration into personality components (which includes schizotypal personality disorder) that contribute to and/or increase risk of the deterioration into schizophrenia⁴ ⁶ ⁷. The biggest contribution to the full picture of schizophrenia development is Paul Meehl’s model involving schizotypes - a person with schizotypy⁴ ⁶ ⁷ ⁸.

*Important note: Schizotypes span a range of function to dysfunction. Being a schizotype does not necessarily mean there is a diagnosis or a disorder present⁴ ⁶ ⁷. This gets super complex, so I made some charts for visual understanding. I encourage you to read more of Meehl’s work⁶ ⁷ ⁸ for more detailed information.

When a human is first developing, everything is determined by genetic materials (DNA), which impacts their personality possibilities. For schizotypes, this DNA is the schizogene(s). Next, the schizogene(s) set up the structure of the brain to involve the neural circuitry (schizotaxia - cognitive slippage). Now, there are other things such as social learning influences (i.e., attachment, interpersonal dynamics) that can create variation in this process, but the outcome will still be schizotaxia. Difficult social learning influences might lead to increased risk of psychosis, while amazing social learning influences might result in decreased risk of psychosis.

From here, the schizotaxic brain is influenced by other internal factors that Meehl called “stressors and polygenetic potentiators,”such as introversion, aggressivity, anxiety proneness, anhedonia, etc⁶ ⁷. These things will determine different personality traits and factors, but it will still lead to a personality organization of schizotypy. And this is where we cross the line (“plane of observation") into what is observable by others, which Meehl⁴ ⁶ ⁷ called the “manifest level.”

In the observable, manifest level is where we see different presentations of the schizotype, such as schizophrenia, schizotypic disorders⁴ ⁶ ⁷ (e.g., schizotypal personality disorder, paranoid personality disorder), and schizophrenia related psychoses (e.g., delusional disorder). Now, the interesting thing here is that there may be schizotypes that do not actually cross that observational line, somehow compensating so well that others do not see them as schizotypic. Which brings us to the question - where does schizoid personality disorder fall?

Schizoid and Schizotypy

There are, of course, differing views of how schizoid personalities fit in with schizotypy⁴. Some propose they are completely separate, while others believe they somehow fit within Meehl’s model of schizotypes⁴. I won’t get into the weeds here, but I hypothesize that schizoids veer off the path after schizotypy personality organization (making them a schizotype), but before the plane of observation due to low neuroticism and antagonism (which are polygenetic potentiators). This matches with the psychodynamic² ³ view that the schizoid continuum ranges from schizoid and schizotypal personalities (nonpsychotic) through schizophrenia (psychotic).

In conclusion, there are significant similarities AND differences between schizoid, schizotypal, and schizophrenia…and schizotypy. Those in the psychology field are still debating various aspects of how they relate. It’s super complex, and I want to know what you think!
